Improved 3D late gadolinium enhancement MRI for patients with arrhythmia or heart rate variability
نویسندگان
چکیده
Background Arrhythmia and heart rate variability have adverse effects on the image quality of Late Gadolinium Enhancement (LGE). Due to the incomplete recovery after an inversion pulse, changes in the RR-interval length induce a k-space weighting, which results in ghosting artifacts in the images. While the impact of heart-rate variability is less pronounced in 2D LGE due to short scan times (10-15 sec), it often results in non-diagnostic image quality in 3D LGE (scan time 6-10 min). Our aim is to develop a novel LGE imaging sequence for patients with heart rate variability or arrhythmia.

3D free-breathing late gadolinium enhancement 3T MRI: comparison with standard 2D Imaging
Background Clinical cardiovascular magnetic resonance imaging (CMR) is routinely performed during multiple breathholds in predefined 2D image orientations. 3D CMR is desirable, since it allows post-acquisition reformatting in any desired imaging plane. However, 3D CMR is hampered by long breath-hold duration, introducing patient discomfort and technical limitations. These limitations can be ove...

PURPOSE To develop arrhythmia-insensitive inversion recovery sequences for improved visualization of myocardial scar and quantification of diffuse fibrosis. METHODS A novel preparation pre-pulse, called saturation pulse prepared heart-rate-independent inversion recovery, is introduced, which consists of a combination of saturation and inversion pulses to remove the magnetization history in ea...

متن کاملImproved late gadolinium enhancement imaging of left ventricle with isotropic spatial resolution
Background Recent studies have shown the prognostic value of the infarct border zone of late gadolinium enhancement (LGE) images in patients with myocardial infarction [1]. This border zone has also been associated with ventricular arrhythmia [2,3]. The accuracy of the characterization of this area depends on spatial resolution of the imaging. 3D LGE allows improved spatial resolution, especial...
متن کامل[Evidence of gadolinium late-enhancement on cardiac magnetic resonance imaging in a patient with peripartum cardiomyopathy].
Peripartum cardiomyopathy (PPCM) is a form of heart failure that affects women late in pregnancy or early in peripartum. The present report describes a case of a patient with PPCM demonstrated by magnetic resonance imaging (MRI) with late gadolinium enhancement of the left ventricle (LV). The late gadolinium enhancement of MRI improved associated with recovery of cardiac function. Endomyocardia...
